All I can say is WOW.....what a difference. Just hooked up my PID controller from Frozone and it is fantastic. Takes a lot of issues away from trying to keep my Lee 20# pot at the right temp. Boolits have improved dramatically and it is going 10 times faster not having to try to wait for pot to heat up if it gets too cold and I miss it , or too hot if I am not paying attention. All automatic now..... Thanks for the great unit Frozone, top quality to boot. The warning lights at too high or too low temp get your attention real quick if things get out of the "zone". Again, Thanks Frozone.
